As you define your installation's migration plan, consider how the new and changed SMP/E functions might affect the following areas of SMP/E processing. For each item described in SMP/E V3R4 overview, review the "Migration procedures" topic to determine how, or if, the change affects the tasks that are performed at your installation.

Customization

You can customize some SMP/E functions to take advantage of new support after the product is installed. For example, you can tailor SMP/E through the use of installation exit routines or SMPPARM options. This section lists changes to SMP/E that might require you to tailor SMP/E to ensure that it runs as before.

Operations

The new SMP/E release might introduce changes to its operating characteristics, such as changed commands, new or changed messages, or in the methods of implementing new functions. This information identifies those changes for which you should provide user education before using this release of SMP/E.

Programming

To ensure that existing programs run as before, programmers who develop programs that use the GIMAPI, library change file records, or UNIX shell scripts must be aware of any changes to those interfaces introduced in a new release of SMP/E.
